Answer:
$3.34
Step-by-step explanation:
$1.39 x 2.4 = $3.336
X=2. You use substitution to put the y=3x-5 into 6x+3y=15.
So you get 6x+3(3x-5)=15
=6x+9x-15=15
add 15 on both sides to get the x's alone and add the x's together.
6+9=15 -- 15+15=30
15x=30
30/15 =2
x=2
It is given in the question that
Suppose the supply function for product x is given by

And we have to find how much of product x is produced when px = $600 and pz = $60.
And for that, we have to substitute 600 for px and 60 for pz, and on doing so, we will get

And that's the required answer .
Let s represent number of shirts and h represent number of hats.
We have been given that the organizers of a talent show have budgeted $1800 to buy souvenir clothing to sell at the event. They can buy shirts for $10 each and hats for $8 each.
The cost of s shirts would be
and cost of h hats would be
. The cost of s shirts and h hats should be less than or equal to 1800. We can represent this information in an inequality as:

We are also told that organizers plan to buy at least 5 times as many shirts as hats. This means that number of shirts should be greater than or equal to 5 times hats. We can represent this information in an inequality as:

Therefore, the second inequality should be
and option C is the correct choice.
